QGE were part of a research consortium with the University of QLD (UQ), Powerlink, Manitoba Hydro and other parties to model the effects on the electricity grid based on the Queensland Government’s 50% renewable energy target for 2030 and beyond.
Connection of generators to the electrical grid is technically complex and requires dynamic modelling to ensure ongoing stability of the power system. The present transformation to renewable energy and battery storage is forecast to increase over the coming decades. This means that many new renewable generators and grid support technologies will need to be connected within Australia in a relatively short period.
QGE achieved the following technical objectives:
Grid system strength and impedances have a significant impact on model performance and benchmark alignment. This can result in system instabilities which can be hard to overcome. Instabilities were resolved by QGE’s engineers, enabling the rapid deployment of the connected models in the state-wide QLD grid model.
The models and deployment methods developed by QGE were successfully deployed by the research team. The parameterized, resizable generation models can be created with acceptable alignment between PSCAD and PSS/E modelling packages, and can be rapidly deployed at a given grid connection point enabling a resizable model to be installed at multiple grid locations within hours.
QGE are recognised leaders in hazardous areas and in grid connected solar PV, which is only possible because of our rock-solid foundation in electrical and controls engineering. We have the knowledge and experience to provide a cost-effective solution, whatever the problem.
Our cloud software, controls and telemetry solutions, and grid export control panels are all products of our ongoing investments in new technology and engineering processes, and we continue to push the boundaries with involvement in blockchain and peer-to-peer energy trading.
At QGE we genuinely enjoy what we do, which means we're always willing to go the extra mile for our customers to deliver the right solution. We have great client relationships because people like working with us.
The QGE team understood the project's constraints and requirements, and were able to deliver a commercial solution that has allowed Agrimin to achieve a higher renewables penetration and lower energy cost than it had expected.
Over several years, QGE have provided control systems design and on site support for upgrades and expansion projects. We've been very satisfied with the quality of their solutions and the high level of support they have provided our remote mine site.
QGE have worked with us for several years on hazardous area issues and have classified a number of our facilities, including new-technology processes, where we've been very satisfied with the pragmatic approach they've taken and the outcomes for our business.
